TOP Media is owned by Shinhwa member Andy Lee, and also includes the groups Teen Top and UP10TION.

The group have released 4 albums to date: ‘We 100%’, ‘Guy Like Me’, ‘Real 100%’ and ‘Sunkiss’.

Before 100%’s formation, Rok Hyun was previously a member of another of Andy’s acts – a duo called Jumper. Leader Min Woo took part in some of Andy solo promotions, as well as having numerous acting roles including the drama The King and I (2007) and the movie Where are you Going? (2009).

The members of 100% have taken part in two variety programmes alongside their successful label mates Teen Top. Both ‘Teen Top Rising 100%’ and ‘Teen Top & 100% Rising Brothers’ were shows that featured both groups competing, having fun and undertaking missions together. The group, or some of its members have also made appearances on many other programmes including: After School Club, Immortal Songs 2 and Let’s go Dream Team to name a few.

In 2013, a sub-unit of 100% called 100% V was formed which comprised of Rok Hyun, Jong Hwan, Hyuk Jin and a rapper called Chanyong. They released a self-titled single album the same year.

In early 2014, leader Min Woo decided it was time to embark upon his military service, and maknae Sanghyun decided to go on an indefinite hiatus from the group whilst he considered what he wanted to do with his future. Despite only having 5 active members, 100% continue to work, with their last mini album released in March 2014.
